I began by testing several free online scripts from websites like The
for that PSP on my credit card, a calculator seemed like a good first script to try. After a few modifications and a
bit of reformatting of the free code, PSPCalc resulted.
While it was interesting to confirm my huge debt by using the PSP that had caused it, PSPCalc didn?t make for a very
exciting game. A bit more experimenting revealed that a Tic-Tac-Toe script also worked in the PSP browser and I ended
up with PSPTicTacToe. It appeared that the browser could run games, but
could they be as complex as, say, Tetris?
Surprisingly, the answer was yes. Using techniques known to work on the PSP and some basic sample Tetris code, I was
able to create PSPTetris. This required a number of compatibility and formatting considerations since practically none
another interesting challenge. The controls still aren?t perfect and there?s no catchy music (unless you consider the
Wipeout menu beat catchy), but PSPTetris should be very playable even in this first version.
How to Run PSPTetris
1. If you don?t already have a portal that lets you browse the web with your PSP (via DNS or proxy), complete
Engadget?s HOW-TO: Get RSS feeds on your PSP. The parts
involving Bloglines are optional.
2. Use the PSP browser to navigate to http://webtopsp.com and select PSPTetris from
the list. If you actually enjoy using the PSP?s ?keyboard?, you can also go directly to
3. Once the page has finished loading, push X on the PSP to play.
Use left/right on the PSP?s directional pad to move a block, down to drop, and X to rotate. You can pause the game
by using the PSP?s power button (sleep mode). This way, you should be able to actually take the PSP away from the
wireless network (it will disconnect anyways) and play PSPTetris anywhere as long as you don?t change the
PSPTetris has four levels (speeds). The level increases with every 10 lines until you reach level 4 (after which you
just have to outlast your battery). Lines give more points at higher levels. Use the game?s ?SET LEVEL? button before
?START/RESET? to start at a specific level.
There are several bugs/glitches due to the PSP browser?s limitations and the early version of the script. They
One of the images may not load properly and remain a white square. The box showing the next block may also be
unaligned or have an unusual border. Refresh the page if any of these things happen (?O? button on the PSP).
The controls were implemented in a somewhat unusual way and require a small square and a few dots to flash to
the right of the board. Try to ignore them.
The X button can be unresponsive (noticeable at higher speeds).
Holding the drop button may leave a color square on the way down. The game will correct this once the block is
Sometimes after selecting ?START/RESET?, the block will appear but not move down. You need to disconnect (?quit?
using the PSP?s Start button) and reconnect to fix this.
Feel free to use a regular web browser to visit the links above if you want to have a peek at the code. You may
modify and re-host the scripts if you wish. Perhaps new PSP-friendly online games will appear now that more of the PSP
Browser?s capabilities have been revealed.
